Just adding to other suggestions and making a few comments...
If you live a place like with weather like Southern California, I'd suggest that you can skip out on the more expensive super high quality floor mats like 3DMaxpider and go for some 1/3 to 1/2 of the price. I went with these:

As for accessories, a center console tray is crucial:. I went with this one:

It's very nice when you get matching cupholder set.
I also found that puddle lights with the Tesla logo (or model logo) were a great luxury accessory that I wouldn't want to go without.
The Novak USB splitter was created by a user of this TMC forum, and I find it essential for getting faster USB charging speed. One side is also conveniently dedicated to data as well.

Lots of folks like the Jeda wireless pad. I think it's a likely a good product based on all of the reviews. I went with this money-saving option...works just fine... also highly-rated at less than half cost:

I have no found a hub to be necessary, but it could be nice to help hide the wires. It depends on how much stuff you're plugging in as well. I wouldn't spend 100 just to hide wires that are usually hidden anyway by the center console. But, if it helps you organize a bunch of different wires for a bunch of different devices, then it may be worth it.
Center console wrap and PPF are good areas to spend any extra cash lying around.
Finally, don't go cheap on the screen protector. 9H tempered glass is the best way to go... check Abstract Ocean. I got the 5H, which is really good (And cheaper), but I probably should've done the tempered glass and probably will eventually.
bonus: tinted windows for sunny/hot climates, a magnetic phone mount (useful to keep your hands from holding a device and potentially getting a traffic ticket), brighter trunk lights
Does anyone know if you can replace those weak standard dome lights??
